Kala-Azar and the Sandfly

چکیده
The author has calculated the role of such insects (phlebotomus) in the spread of the disease. He concluded that from 172,000 phlebotomi biting human beings only one has the probability of being infective and the phlebotomi must become infective by biting such dogs and not by biting human beings. Having been told that some cases of kala-azar have occurred in a country town, Coviltra, at a 2,000-2,200 feet altitude, the author made a survey during the months of August and September (two of the best months lor finding these insects) and has found such a small ^mber of phlebotomi that he could not justify their role in the transmission of the disease. . . . The author has found leishmaniae in the nasal mucus of a relatively high number of patients and suggests that new investigations ought to be done on the epidemiology ?f kala-azar, having in mind the possibility of direct contagion, because he found a very high percentage ?i patients (81,870) with leishmania in the nasal mucus
